Ratio of temperatures for two samples of He and UF 6 that produce same collision frequency with vessel walls is to be determined. Concept introduction: Anything that has mass and accommodates some space is called matter. Three common states of matter are solids, liquids and gases. Gas is state of matter that neither has specific shape and volume. It can take up volume of container in which it is kept. Negligible intermolecular forces arise between molecules of gases. Gas molecules undergo collisions with each other and also with container walls.

Question

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

1. A flask contains 155 cm of hydrogen collected at a pressure of 22.5 kPa. Under what pressure would the gas have a volume of 90.0 cm at the same temperature? (Recall that 1 cm =1 mL.) 2. If the pressure exerted on a 300.0 mL sample of hydrogen gas at con- stant temperature is increased from 0.500 atm to 0.750 atm, what will be the final volume of the sample?

8. For the reaction 2H₂O(1) + 2e¯ → H₂(g) + 2OH(aq), calculate the volume of "dry" hydrogen gas created at a pressure of 745 mm Hg and 25.0 °C when 0.6696 g H₂O are used. The vapor pressure of water at this temperature is 23.8 mmHg. A) 0.479 L B) 0.464 L C) 0.450 L D) 4.18 L E) 4.05 L

12. A sample of solid potassium chlorate was heated in a test tube and decomposed into potassium chloride and oxygen gas. The oxygen produced was collected by displacement of water at 22ºC at a total pressure of 754 torr. The volume of the gas collected was 0.650 L, and the vapor pressure of water at 22ºC is 21 torr. Calculate the partial pressure of O2 in the gas collected and the mass of potassium chlorate in the sample that was decomposed. (2.13 g)
